My journey with rectal cancer: What's your experience?

Hello everyone. I live in the UK and was diagnosed with rectal cancer 2 weeks ago. Since then I've been fast tracked through our NHS system with an MRI scan, CT scan, and another MRI scan this coming Monday to check out a spot on my liver, followed by a meeting with a consultant.
I've been told the tumour is 6" inside from my anus. Can anyone inform me if this would be rated low, mid, or high up in the rectum? Thanks.
This is a great forum for exchanging information. Hats off to the Mayo Clinic!
